Answer:

The ratio of sanstone to marble is... 141414 : 333

All you have to do is look at how much sandstone Dean has and how much marble he has, then put the amount of sandstone infront of the amount of marble because in the question it says what is the ratio of sandstone to marble and you see that sandstone is first.

Hope this helps! :)

Explanation:

The reflection rule we use is

[tex](x,y) \to (-x, y)[/tex]

when we want to reflect over the y axis. The x coordinate flips from positive to negative, or vice versa, while the y coordinate stays the same.

Therefore, [tex](1, -5) \to (-1, -5)[/tex]

Answer:

225 square feet

Step-by-step explanation:

the base of the pyramid would be 76 ft², since 12*6=72. Then you get the surface area of the sides. 2 of the sides would be 48 ft², since (12*8)/2=48. The other 2 sides would be 28.5 ft², since (6*9.5)/2-28.5. Then you just add the surface areas of all the sides; 76+48+48+28.5+28.5 to get 225.

Hope this helps! :)

The number of CDs of another type of music will be 21.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Harrison has 70 CDs in his music collection. If 10% of the CDs are country music and 60% are pop music.

The percentage of the other CDs will be:-

P = 100 - 60 - 10

P = 30%

The number of the other CDs will be:-

Number = 70 x 30%

Number = 70 x ( 30 / 100 )

Number = 21

Answer:

Step-by-step explanation:

In non-mathematical form, the question is asking $8.80 is what percent of $440. N will equal the percent. So, you would set up the equation like this: 20 = N · 440

You need to solve the equation.

20/440 = N · 440/440

0.045 repeating = N

4 is greater than 3, 5 is greater than 4.

Answer:

35 times 5/7

Step-by-step explanation:

5/7 is a decimal and when multiplied by 35 it turns into 25 days. 25/35 is 5/7 so the answer makes sense

Answer:

25 Days

Step-by-step explanation:

Do 5/7 * 5/5 and then you get 25/35 which the numerator is how many days he went out of those 35 days

Answer:

It would be 4

Step-by-step explanation:

When dealing with slope its always going to be rise over run, so 60/15 is 4

Hope this helps :)

Answer: 2/25

Step-by-step explanation:

The formula to find the slope is (y2-y1)/(x2-x1)

If you plug in the numbers, you get (18-14)/(30-(-20))

Solve the expression and you get 4/50 = 2/25

So your answer is 2/25

Answer:

the slope is 2/25.  use the formula m= y2-y1/x2-x1 and plug in the points

Answer:

yes you can and it would be 14x

Answer:

A: 69

Step-by-step explanation:

80% of 115 customers had combos. To find out the amount that had combos, we multiply the amount of customers by percentage. 115 * 80% (0.8) is 92. 92 customers had combo meals. 3/4 of them had fries with it, and 3/4 is 75% in percent form. We multiply 92 by 75% to get the amount that had fries. 92 * 75% (0.75) is 69. There. Sally's Diner had 69 of Friday's customers order fries with their combo meals.

Answer:

-3

Step-by-step explanation:

The x-intercept is 3, here's why

First, you need to get the slope

y2-y1

--------

x2-x1

You should get 2/3

Next, you need to use y=mx+b

y= 2/3x+b

2= 2/3(6)+b       You get 6 and 2 from the coordinates

Once this is worked out you'll get y=2/3x-2

To get the x intercept you need to set y equal to 0

0=2/3x-2

Add 2 to each side

0-2 = 2/3x

Multiply each side by 3/2 to isolate x

-2 *3/2 = 2/3x * 3/2

-3 =x

The x intercept is -3

======================================================

Explanation:

The down payment is $400, so that means they must pay back 1495-400 = 1095 dollars. Let L = 1095 be the amount loaned

The annual interest rate is 28% which means r = 0.28; the monthly interest rate is i = r/12 = 0.28/12 = 0.02333 approximately

There are 12 months in a year, so n = 12 is the number of payment periods

----------------------------------------

In summary so far, we have

Those values will be plugged into the monthly payment formula below

M = L*( i*(1+i)^n )/( (1+i)^n - 1 )

M = 1095*( 0.02333*(1+0.02333)^12 )/( (1+0.02333)^12 - 1 )

M = 105.671914631108

M = 105.67

The monthly payment is $105.67

If they have a monthly payment of $105.67, and they pay that for 12 months, then 12*105.67 = 1,268.04 dollars is the amount of money they pay back to the credit card company.

The total amount of interest would be 1,268.04 - 1,095 = 173.04 dollars

Side note: the formula is a complicated ugly mess, so it's understandable to use calculators that already have the formula built in. Many websites offer free calculators that do this.
